Simply turning on some music and dancing with your kids is a lovely way to spend an afternoon. Have a competition for the craziest dance move, try your hand at breakdancing, bellydancing or even keeping a hula hoop up. It's remarkable how much entertainment a couple of balloons can create too. See who can win at the ‘keeping them from touching the floor’ game – you never know, they may have an Olympic career ahead of them. The only equipment you'll need is a good soundtrack!
